Resolution

This issue is fixed in Symantec Endpoint Protection 14.3 RU4 and 14.3 RU2 P2. For information on how to obtain the latest build of Symantec Endpoint Protection, see Download the latest version of Symantec software here.

If upgrading is not an option at this time the following workaround can be implemented:
